Abstract

A premix pilot nozzle (114) is disclosed herein. The premix pilot nozzle (114) includes a nozzle body (124). The nozzle body (124) includes a forward wall (126), an aft wall (128), an outer band (130) that extends between the forward wall (126) and the aft wall (128) and a tip portion (132) that extends axially downstream from the aft wall (128). The nozzle body (124) further defines a fuel inlet plenum (138) that extends coaxially within the nozzle body (124), a fuel distribution plenum (142) that is defined within the nozzle body (124) radially outwardly from and in fluid communication with the fuel inlet plenum (138), a plurality of premix passages (150) that extend helically around the fuel inlet plenum (138) within the fuel distribution plenum (142) and a plurality of air passages (158) annularly arranged around the plurality of premix passages (150). One or more premix passages (150) of the plurality of premix passages (150) are in fluid communication with the fuel distribution plenum (142).
